Abstract
Two photographic methods for leak testing sealed sources of radium 226 have been documented. Both procedures use high-speed photographic emulsion to detect light produced by interactions between a ZnS screen and alpha particles emitted by leaking sources. The Polaroid Lane 4 x 5 film system, which includes individually packeted photographic film and film holder, is used in these methods. (Author)
